this i osltion the load may be carried to a: stack or wagon as desired,and dumped, When lowering the fork the operator manip-f ulates theclutch controlling lever in a manner to loosen the pressure upon thefriction clutch-members sufficient to allow the weight .of the fork torotate the hoisting drum through its cable connections therewith. Theinitial movement of the hoisting mechanism acts directly upon theforward end of the fork" carrying frame by means of the hoisting cablepassing over the sheave 84 and to theroller 87, and swings it upwarduntil the'axis of the'roller 87" passes above one end of sheave 84, thenbelow, passing directly to the connection of the cable with the lowerends of bars 88, each having their upper ends connected with the rearend of the swinging frame 41, that is connected with the fork carryingframe. The upward movement of the latter is continued until apredetermined height is reached, when the flexi-- bl'e connectionbetween frame 41 and the clutch controlling lever will cause the toothedclutch members to become disengaged and, the fork will remain stationaryunder the frictional engagement of the cone clutch members as controlledby the pres sure regulating springs and the pawl engaging with theratchetteeth upon the clutch member 49.
